Have been playing with the Delta 2 max and love it so far. My only problem is that I need more cord from the generator to the solar panels. I will order a longer cord and should be happy with it. I love the app and how easy it is to use.
I live full time on the road and I needed 24-hour power to run my eco flow glacier cooler and charge laptop phone microwave etc I have a 400 watt solar panel from another company. I thought the ones on eco Flow looked kind of flimsy and had bad reviews. But anyway the Delta max 2 works amazing last 5 days on a charge, 5% charge to 100% in an hour and a half plugged in to AC. Also charge about 4 hours from solar panel. Very quiet hardly noticeable
Got this for power outages. Very nice that it has two solar ports. It does what it is supposed to do. Frame is well built. Very easy to use. I only use solar to charge it. Thank you.
Have not been able to use the product except to test all components. Look forward to exploring some more of the possibilities when I have time.
I have a cabin on a piece of land I own that doesn't have electricity so I have been searching for something to power my CPAP (Resmed AirSense 11) instead of using a car battery with an inverter. I managed to get 8 days of usage out of the unit with the spare battery. I was using the AC power and did have the heated tube on along with the humidifier. Average usage per day was right at 11hrs. I have yet to see how long it can go using DC power and without the heated tube or humidifier, but I would assume it would go much further than 8 days. Hands down beyond pleased with this unit and the spare battery!

I was a DIY solar power wannabe... that is 'til I connected with Manny... The man's a prince! He not only knows his stuff; he walked me through all things electrical. To make sure I had all I needed... he gave me his cell phone # to text him anytime I got confused... nights and weekends included. The prices were very competitive... definitely go with Manny -- you won't go wrong!

I am always hesitant to buy things at places I have never shopped... I want to give a shout out to Manny who with great patience and knowledge helped me get my orders... I felt valued as a customer and I will definitely be back in the future. I highly recommend them, they make you feel like family.

I'm about to go off grid. I called Manny, he walked me through everything so I could truly understand what I needed and never tried to upsell me. He was honest and made a customer for life.
Ray B.
I would personally like to thank Manny... I purchased the inverter and decided I needed to return it... Manny was very understanding and went out of his way to help me return the product and not even have to pay for shipping return. He gives this company reputation, honor and quality customer service!
Roger V.
I have been talking with Manny the owner... He has not only helped me design a system but he's been assisting with the install and components. I am super pleased so far with the assistance.
